I have this arrays :
$a = array(
'key1' => array ( 'k1'=>'value1', 'k2'=>'value2' , 'k3'='' ),
'key2' => array ( 'k1'=开发者_Go百科>'value1', 'k2'=>'value2' , 'k3'='' ),
...
);
and I have another array:
$b = array('key1'=>'value array b key 1'),
'key2'=>'value array b key 2'),
...
);
I need to get the values from array $b and put in array $a in key 'k3', I am using this function to do this:
foreach($a as $key => $item) {
$a[$key]['key3'] = $b[$key];
}
Its works for me, but I d like to know if there is a better and simplier way to do that, something using array_map....
Anyone has some idea ?
Your code is way easier to understand. The array_walk
(not map, since the return value does not matter) equivalent would be
array_walk($b, function($el, $k, $a) {$a[$k]['key3'] = $el;}, &$a);
